Abstract: | This paper analyzes the running mechanism of flexible and thin tape above rotating protrusion through a numerical simulation.
The scope of analysis is confined to the phenomena of elastohydrodynamic lubrication between the rotating drum with a protrusion
and the running tape. This model is based on the modified Reynolds equation and the equation of plate considering the effect
of geometric nonlinearity and geometry of protrusion. Finite element method of Bubnov-Galerkin type is adopted as a numerical
simulation technique to solve the above two coupled nonlinear equations. In numerical simulation, the influences of tape tension
and protrusion velocity are evaluated in simple model. In complex models, the reciprocal action of two protrusions is simulated. |
